When does art fulfill an expressive function?

Art fulfills an expressive function when it conveys the emotions, thoughts, or experiences of the artist, allowing them to communicate their inner world to others. This can occur through various mediums, such as painting, music, or literature, where the artist's feelings and perspectives are embodied in their work. Additionally, art can evoke a similar emotional response in the audience, facilitating a shared understanding or connection. Ultimately, it serves as a powerful means of personal and collective expression.
